Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing codes.
C. Determine if an associated code is active or logged. Table 2 lists associated codes.
Codes
Result: An associated code is active.
Repair: Refer to the appropriate procedure to troubleshoot the associated code.
Result: An associated code is not active or logged.
Proceed to Test Step 2.
Result: An E1690 or 105 code is active.
Proceed to Test Step 2.
Result: A code is not active or logged.
Proceed to Test Step 2.
2. Check that the Engine is Properly Equipped for Ambient Temperatures
Note: Refer to the Owners Manual for operation in cold ambient temperatures.
Engine Operation
Result: The engine is equipped for the ambient temperatures.
Proceed to Test Step 3.
Result: The engine is not equipped for the ambient temperatures.
Repair: Refer to the Owners Manual for operation in cold ambient temperatures.
3. Check the Operation of the Cooling Fan
A. Verify that the cooling fan that is being used to transfer heat from the ATAAC is working properly.
B. If the fan is belt driven, verify that the clutch is operating properly. A fan that is locked on will cause over cooling of the inlet air.
C. If the fan is hydraulically driven, verify that there is no leakage around the motor and that the pressure for the fan is adequate. Verify that the correct hydraulic fluid is being used for cold-weather operation.
Cooling Fan
Result: The fan drive system is working properly.
Proceed to Test Step 4.
Result: The fan drive system is not working properly.
Repair: Make the necessary adjustments to the clutch, if the fan is mechanically driven . Refer to the machine Test and Adjust for the proper procedure. Repair leaks or make the necessary adjustments to the motor or the hydraulic pump if the fan is hydraulically driven. Use the appropriate hydraulic fluid for cold-weather operation. Refer to the Testing and Adjusting manual for the proper procedure.
If the problem still exists, proceed to Test Step 4.
4. Check the Operation of the Intake Manifold Air Temperature Sensor
A. Remove the intake manifold air temperature sensor. Allow the intake manifold air temperature sensor to rest in ambient air for 2 minutes.
B. Connect to the engine ECM by using Cat ET.
C. Monitor the value of the intake manifold air temperature sensor on Cat ET.
Sensor
Result: The value of the intake manifold air temperature sensor is within −9° C ( 15° F) of the ambient temperature.
Repair: Reinstall the sensor. Torque the sensor to the proper specifications. Return the unit to service.
Result: The value of the intake manifold air temperature sensor is not within −9° C ( 15° F) of the ambient temperature.
Repair: Replace the intake manifold air temperature sensor. Return the unit to service.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solution Network (DSN).
